New derivatives of thiazolo[5,4-b]pyridine (I) and 3,6-diazaphenothiazine (II) are described. The yields of products spotlight a definite trend in the role of substituents in the conversion of pyridine derivatives to thiazolo[5,4-b]pyridines. Some derivatives of these compounds were hydrolyzed and converted to nitrothienyl pyridyl sulfides of antibacterial and pesticidal interests by reacting with 2-bromo-3,5-dinitrothiophene. The latter similarly reacts with aminopyridines to yield thienyl aminopyridines. In an attempt to convert 7-methoxy- and 7-chloro-1-nitro-3,6-diazaphenothiazines to their dinitro-3,6-diazaphenothiazine derivatives, only 7-methoxy- and 7-chloro-1-nitro-3,6-diazaphenothiazine sulfoxides, identified by their strong sulfoxide band in the 1035-to 1045-cm-1 region, were obtained.
